How to improve the efficiency of rubber extruder barrel screw?The reason for the noise of the barrel screw of the rubber extruder:
1. The assembly gap between the screw barrel of the rubber extruder and its supporting transmission shaft is too large. During rotation, the center lines of the two shafts are not concentric, and the error is too large.
Second, the screw extruder of the rubber extruder is bent and deformed, and the straightness of the center line of the shaft is too large.
3. The perpendicularity between the end surface of the screw barrel of the rubber extruder and the flange of the machine base and the center line of the barrel cannot be guaranteed, and the error is large.
Fourth, the screw barrel of the rubber extruder is assembled in the barrel of the extruder, and the concentricity error of the two parts is large.

How to improve the use efficiency of the barrel screw of rubber extruder?
First, each plastic raw material has an ideal plasticizing processing temperature range, so the processing temperature of the barrel should be controlled to make it close to this temperature range.
Second, the speed should be adjusted properly.
Because some plastics are added with reinforcement, such as glass fiber, minerals or other fillers. The friction of these substances on metal materials is often much greater than that of molten plastics. In the injection of these plastics, if the high speed is used, the shear force on the plastic will be increased, and the reinforcement will accordingly produce more shredded fibers. The shredded fibers contain sharp ends, which cause wear The force is greatly increased.
